Description

Technical Field

[0001] The utility model relates to the technical field of six-sided top presses, in particular to a six-sided top press that is easy to operate. Background Art

[0002] The hinged six-sided top press is the most widely used large-cavity press in China. This type of press has the advantages of simple ultra-high pressure mold structure, low cost, and easy operation. It is a commonly used equipment for synthesizing superhard materials such as diamond and cubic boron nitride in China.

[0003] The main structure of the hinged six-sided press consists of six hinged beams, twelve pins, six working cylinders, a machine base, and protective devices. The six working cylinders are respectively installed on the six hinged beams, which are hinged with twelve pins to form a hexahedral rigid frame.

[0004] However, technological advancements have led to higher requirements for the size and quality of superhard materials, and consequently, the equipment's load-bearing capacity, significantly reducing the lifespan of hinge beams. The primary failure mode is breakage of the hinge beam ears, resulting in high maintenance costs. Because the pin holes in the hinge beam ears are located at the front end of the ears, increasing the thickness of the hinge beam ears reduces the window area within the six-sided press, limiting operation. Therefore, we developed a six-sided press that is easier to operate. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a six-sided top press that is easy to operate.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A six-sided press that is easy to operate includes a pressure beam, a connecting block connected to the pressure beam by a pin shaft, the pressure beams located on the six sides, and the adjacent edges of two adjacent pressure beams are hinged together. Four groups of connecting ears are distributed circumferentially on the outer wall of the pressure beam, and the number of connecting ears in each group is at least two. Connecting ear pin shaft holes are opened on the same axis of each group of connecting ears, and the minimum straight-line distance from the connecting ear pin shaft hole to the center of the hexahedron structure is 0.7 times to 2 times the minimum vertical distance from the center of the hexahedron structure to the bottom surface of the piston cavity.

[0008] Preferably, when one end of the connecting block is connected to the connecting ear, the connecting block cannot rotate freely around the pin.

[0009] Preferably, a limiting block is protrudingly provided on the outer wall of the pressure beam, and the end face of the connecting block is in contact with the limiting block, so that the free rotation of the connecting block is limited by the limiting block.

[0010] Preferably, the pin is a non-circular pin.

[0011] Preferably, there is one connecting block connected to a single set of connecting ears, and the connecting block is inserted between the connecting ears.

[0012] Preferably, there are multiple connection blocks connected to a single set of connection ears, and the connection blocks are connected to the connection ears alternately.

[0013] The beneficial effects of the utility model are:

[0014] 1. Compared with the traditional hinged six-sided press, the easy-to-operate six-sided press proposed by the present invention moves the pin shaft hole of the connecting ear backward and connects with the connecting block and the pin shaft, which effectively saves the space in the middle of the six-sided press. When the thickness of the connecting ear is increased, the six-sided press still has a larger operating window, ensuring that the production operation can be carried out smoothly.

[0015] 2. The easy-to-operate six-sided top press proposed in the utility model moves the pin shaft hole of the connecting ear backward, so that the length of the area on the connecting ear subjected to the pin shaft tension is significantly increased. When the thickness of the connecting ear remains unchanged, it can greatly improve the tensile performance of the connecting ear, and the press structure can withstand higher working pressure; on the other hand, after the pin shaft hole on the connecting ear is moved backward, the connecting ear can form a whole with the area on the pressure beam located at the rear of the piston cavity, further improving the tensile performance of the connecting ear.

[0016] 3. The utility model proposes an easy-to-operate six-sided top press. When one end of the connecting block is connected to the connecting ear, the connecting block cannot rotate freely around the pin shaft. When the six-sided top press is assembled, the connecting block cannot rotate, and there is no need to limit the connecting block, which improves the installation efficiency. When the six-sided top press is disassembled, the connecting block cannot rotate, which prevents the connecting block from suddenly rotating and hitting the operator or other objects, thereby improving the safety of the device.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-7A six-sided top press machine that is easy to operate includes a pressure beam 1 and a connecting block 2 connected to the pressure beam 1 through a pin 3. There are six pressure beams 1, and adjacent pressure beams 1 are perpendicular to each other and distributed in six directions. They are connected to form a hexahedral structure through the pin 3 and the connecting block 2. A piston cavity 13 is opened on the side of the pressure beam 1 facing the center of the hexahedral structure. Four groups of connecting ears 11 are distributed circumferentially on the outer wall of the pressure beam 1. The number of connecting ears 11 in each group is at least two. The same axis of the connecting ears 11 is provided with connecting ear pin holes 12, the connecting block 2 is inserted between each set of connecting ears 11, and a connecting block pin hole is provided at the end of the connecting block 2. The pin 3 is inserted into the connecting ear pin hole 12 and the connecting block pin hole. The minimum straight-line distance from the connecting ear pin hole 12 to the center of the hexahedron structure is 0.7 times to 2 times the minimum vertical distance from the center of the hexahedron structure to the bottom surface of the piston cavity 13, that is, the connecting ear pin hole 12 is located near the bottom surface of the piston cavity 13 or behind the bottom surface of the piston cavity 13. Figure 4-7 In the embodiment, the number of each group of connecting ears 11 is three, Figure 4 In the middle, the connecting ear pin shaft hole 12 is close to the bottom surface of the piston chamber 13, Figure 5-7 In the embodiment, the connecting ear pin shaft hole 12 is located in different areas behind the piston chamber 13.

[0031] When one end of the connecting block 2 is connected to the connecting ear 11 , the connecting block 2 cannot freely rotate around the pin 3 .

[0032] There is only one connecting block 2 connected to a single set of connecting ears 11 , and the connecting block 2 is inserted between the connecting ears 11 .

[0033] There are multiple connecting blocks 2 connected to a single group of connecting ears 11, and the connecting blocks 2 are alternately connected to the connecting ears 11. In this case, the connecting blocks 2 connected to the same group can be split, that is, the connecting blocks 2 are independent of each other, or they can be integral, that is, the connecting blocks 2 are fixedly connected by fixing rods.

[0034] When one end of the connecting block 2 is connected to the connecting ear 11 , the connecting block 2 cannot freely rotate around the pin 3 .

[0035] In Example 1, Figure 8 As shown, a limiting block 14 is protrudingly provided on the outer wall of the pressure beam 1 , and the end face of the connecting block 2 contacts the limiting block 14 , so that the free rotation of the connecting block 2 is limited by the limiting block 14 .

[0036] In Example 2, Figure 9-11 As shown, the pin 3 is a non-circular pin. Figure 9 The middle pin 3 is a square with rounded corners. Figure 10 The middle pin 3 is oval. Figure 11 The middle pin 3 is a circle with a groove, and the pin 3 can also be an oblong, a circle with convex strips, etc.

[0037] The easy-to-operate six-sided press proposed by the utility model, compared with the traditional hinged six-sided press, moves the pin shaft hole of the connecting ear backward and cooperates with the connecting block 2 and the pin shaft 3 for connection, effectively saving the space in the middle of the six-sided press. When the thickness of the connecting ear 11 is increased, the six-sided press still has a larger operating window, ensuring that the production operation can be carried out smoothly.

[0038] The easy-to-operate six-sided pressing machine proposed in the present invention moves the connecting ear pin shaft hole 12 on the connecting ear 11 backward, so that the length of the area on the connecting ear 11 subjected to the tension of the pin shaft 3 is significantly increased. When the thickness of the connecting ear 11 remains unchanged, it can greatly improve the tensile performance of the connecting ear 11; on the other hand, after the connecting ear pin shaft hole 12 on the connecting ear 11 is moved backward, the connecting ear 11 can form a whole with the area on the pressure beam 1 located at the rear of the piston cavity, further improving the tensile performance of the connecting ear.

[0039] The utility model provides an easy-to-operate six-sided pressing machine. When one end of the connecting block 2 is connected to the connecting ear 11, the connecting block 2 cannot rotate freely around the pin shaft 3. When the six-sided pressing machine is assembled, the connecting block 2 cannot rotate, and there is no need to limit the connecting block 2, thereby improving the installation efficiency. When the six-sided pressing machine is disassembled, the connecting block 2 cannot rotate, thereby preventing the connecting block 2 from suddenly rotating and hitting the operator or other objects, thereby improving the safety of the device.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
